Look for problems on other sites.
This item is especially suitable for beginners who have no readers at all. You just need to find a forum or social network on your subject and see what people are discussing on these resources and what questions they ask.
You may want to go to large sites with high traffic and active communication to get excellent results. However, having spent plenty of time in small forums, you will be surprised how often people ask the same questions.
There is no absolutely perfect site, everything can always be improved, so that you will go forward to the top, the road will go.
